Davey, P., 2009: A local and declining species in England and Wales, the foodplant is unknown. In Dorset, the moth is headquartered in old oak/birch woodland, where it is locally frequent. The species is regularly found in Bracket’s Coppice, Melbury Park, Yellowham Wood, Puddletown, Rooksmoor, Piddles Wood, Oakers Wood, Woolland, Trigon, Castle Wood and Boys Wood. Elsewhere, the species has been found in chalky soil localities where ash (Fraxinus excelsior) or elm (Ulmus spp.) grow. The black square-shaped mark two-thirds along the costal edge of the forewing contrasts starkly against the white ground colour and renders this quite a distinctive species.
